If you are using Magento 1.4.1 or just upgraded any of your old Magento sites to the latest Magento version, then you may be getting a very weird error on your checkout page, that the checkout CONTINUE button on payment screen, either on Authorize.net or PayPal , just doesnt work.

The cause of this error is, Magento Team has introduced a new javascript file, which validates the credit card numbers, etc on the payment screen.

So, if you are using the default theme, then you should not get this problem.

But if you are using any custom theme, then you have to do some changes on your files.

Few symptoms of this problem is, you will see such errors,
Please verify the card with the issuer bank

or
Unable to initialize Express Checkout review.

or
CONTINUE button on Credit Card Form doesnt work.

I will give the instructions in details below, how to fix this issue :

This must solve your complete problem .
But in case, its still not working, then here is another fix, which I got from another member from a forum,

I was experiencing the same issue: Nothing happens when you enter the credit card information and hit continue. After investigating with Firebug, it seemed that the method verifyCreditCard was not defined in validation.js.

You can fix this by pasting the following javascript code into validation.js under js->prototype in root folder:

Https is an important part in magento as customer or user gain trust and it increase web site's search engines rank also. To make your login page, register page, checkout page and admin panel as https you need to install SSL certificate into your server first.After Successful installation do the following process .
Go to System->Config->Web
then Click on Secure tab.
Change your base url to https://www.yoursite.com [ Important : Write HTTPS in your base url otherwise it will not work]
Make Use Secure URLs in Frontend to Yes
Make Use Secure URLs in Admin to Yes.

Seethe Below screenshot
Then Save config Clear your cache, Now go to your frontend then click on login page you can see that your login page is changed to https.

2. By Using Magneto clean Up Tool
a.Download the magento clean up tool .
b.Unzip magento-cleanup.php to the root directory where Magento is installed.
c.Browse to http://yourdomain.com/magento-cleanup.php

Default Category page layout is written in page.xml file which resides in app/design/frontend/default/your-theme/layout/. Open Page.xml then change line number 35 or find .
<default translate="label" module="page">
<label>All Pages</label>
<block type="page/html" name="root" output="toHtml" template="page/3columns.phtml">
Change default 3columns.phtml to 1Coloumn.phtml or 2columns-left/right.phtml .Then save and upload it .Clear your cache to see the effects.
Note :: Changing all page layout doesn't effect other pages of magento it effects only the category page. So don't hesitate to change this.

inside template="" you can write your file path. and in name="" you can give proper and unique name , in type="" you can write your module directory also(e.g:- customer/account if you are calling login.phtml file).

One more way to call a phtml file. You can use your layout or xml file to do. For example i am going to attached home.phtml file which reside in cms folder of my thmeme template then I am writing the code given below

In frontend to calll store url we write
<?php echo $this->getUrl('');?>
But in admin Panel we can't write php or echo like statement. So to call base Url in Magento CMS Page or store url you have to write like the code given below.
<a href="{{store url='index.php'}}">Home</a>
{{store url='index.php'}}
This the actually way to call store url in admin panel.
You can use your required link instead of index.php (e.g:- contacts to call Contact us page).

If you are using Id to get a select box value then it's little bit easier . If you don't have id in your select box then you need to use name attribute to select the select box. I have used name tag to get the select box value.

1. Open up your web browser, and type in your Blogger blog’s URL.
2. At the end of the URL add robots.txt.

For example, if the URL of your blog is http://myblog.blogspot.com, then enter http://myblog.blogspot.com/robots.txt
3. Some text should now be displayed in your browser. Look for a line that starts with Sitemap:. The URL after that label is the location of your sitemap.

Using the example above, the line would look like:

Sitemap: http://myblog.blogspot.com/feeds/posts/default?orderby=updated
4. Back in Google’s Webmaster Tools, the domain name part of the URL would already be included, so you would just need to specify the feeds/posts/default?orderby=updated portion of the sitemap URL. If other sites are able to accept a sitemap, then you may need to include the entire URL
